Tank looks great. Wow, the CC21 colony is amazing!
Quoting from reading/listening/watching @Thales, Dong, ..., ammonia "juice is not worth to squeeze". There is no real scientific study, evidence, stats to back it up. Nitrate is safer bet.
Besides copper, tin level is alarming - from searching google/internet:
Potential Harm to Shrimp: While some sources primarily focus on the effects of tin on corals, it's reasonable to infer that high tin levels could also negatively impact reef shrimp given their sensitivity to heavy metals...
So displeased/irked when I received this collection letter yesterday.
I just emailed UPS again and will call them tomorrow.
Any advice on what else I should do to get rid of this?
